FAQs
1. General Questions
Q: What is a CAS Clamp?
A: A CAS Clamp is a precision-engineered rigging clamp designed to join rigging tube securely. It is used in professional film and TV production for camera rigs, car rigs, lock-off rigs, lighting support, and other grip applications.
Q: What sizes are available?
A: Cat O’Nine Engineering produces CAS Clamps in 16 mm, 19mm, 32 mm, and 48 mm tube diameters to cover small, medium, and heavy-duty rigging applications. Each CAS Clamp has also been designed to be interchangeable, allowing the user to rig 16mm to 32mm tube and so on.
Q: What material are CAS Clamps made from?
A: All CAS Clamps are CNC-machined from 6082-T6 aluminium, and finished with a type III hard anodising after bead blasting for corrosion resistance, durability, and reduced reflectivity on set.
Q: Are CAS Clamps compatible with other tube or rigging systems?
A: Yes — CAS Clamps are designed to integrate seamlessly with standard 16 mm, 19mm, 32 mm, and 48 mm rigging systems.
5. Safety & Installation
Q: How do I install a CAS Clamp?
A: Align the clamp over the tube and then tighten bolts evenly to ensure a secure grip. For car rigs and high-load applications, always double-check torque and positioning to maintain safety.
Q: Can CAS Clamps be reused?
A: Yes — they are durable and designed for repeated assembly and disassembly without compromising structural integrity.
Q: Are CAS Clamps safe for on-set use?
A: Absolutely — they are CNC-machined to tight tolerances, anodised for corrosion resistance, and tested for grip applications. Always follow standard safety protocols when mounting cameras or vehicles.
